[GUIDE] - How to roll back Valheim versions

[Chronic213]

Here's a great guide on how to access and download previous/old versions of any game here on Steam. All credit goes to the original author of that guide. All I've done is paste a link.

For anyone who doesn't like the recent changes, it is possible to revert on an individual basis.

https://steamcommunity.com/sharedfiles/filedetails/?id=889624474

The App ID for Valheim is: 892970
The Depot ID for WINDOWS Valheim is: 892972
The Manifest ID for the LAST version of Valheim released Mar 29 (pre hoe mechanics change) is: 1228868947234295527


The line you need to enter in Steam Console to roll back to pre hoe changes is:
download_depot 892970 892972 1228868947234295527

Other than that, follow instruction in the linked guide!

Alternatively, you can swap out the Manifest ID for whatever Windows version you prefer.



NOTE: If you intend to do this to Valheim, you need to be aware that:
- you cannot connect to mismatched version servers.
- you should have a backup of your world files PRE "optterrain"!!! Loading a world that has had "optterrain" run on it in a version of the game that doesn't know what "optterrain" is will likely cause some major issues.
- in order to roll back whole servers, people will need to roll back BOTH client and server files separately.
-do this at our own risk.

ALSO NOTE: I have not done this myself, YET! I intend to, as time allows, today. If I encounter any problems or have any info to add, I will update accordingly.

This may not work as this function has been kinda broken for some time.

Yeah you appear to be correct. Just tried downloading and getting error: "manifest unavailable".

I'm trying to find a solution.

[Manwith Noname]

There's a third party solution called Depot Downloader but use it at your own risk.

Edit:

https://github.com/SteamRE/DepotDownloader

Edit:

Although, reading the issues page, that might not work anymore either.

[Chronic213]

Hmm... yeah I just found the same thing. Haven't tested DepotDownloader yet... but I'm going to.

The guide I found on it is here:
https://steamcommunity.com/sharedfiles/filedetails/?id=2353930763

And comments posted from the Author as recently as Apr 11, so hopefully that's a good sign. This does add steps that some people will likely be unwilling to do, though.

Would be great if we could access the previous versions through the Betas tab, as many EA games do. Just for mod compatibility etc. Should make a suggestion perhaps, if I find the time. Unless someone else does that first. :)

This would absolutely simplify things.

Heh, last time I brought that up the EA defence force came rushing in to say "no".

To mention that, a savegame used in the current version is probably not downward compatible

People said no to having direct access to older versions? I get called EA fanboi often enough, and I totally think that should be available!

Cool to see there's an option for Valheim, even if it's just a workaround. Worth pinning imo... Assuming it works, that is.

[Chronic213]

OK, so the second guide I posted above (comment #4) APPEARS to be working. Currently downloading a previous manifest. Will update soon.

Yeah, go figure. Apparently ensuring your player base can continue having fun in their world when you make potentially save breaking changes shouldn't be supported.

[Chronic213]

SUCCESS!


I followed all steps in the guide I posted in comment 4. It's WAAAY less complicated than those steps make it appear.

Basically:
1. Download the Microsoft dotnet Framework linked in that guide and install.

2. Download THE LATEST VERSION of that DepotDownload software from GitHub ver 2.4.0 (NOTE: The one linked in the guide is NOT the latest... might still work, but there IS a newer one).

3. Navigate to that Depot Download folder in a command prompt window and type:

dotnet DepotDownloader.dll -app 892970 -depot 892972 -manifest 1228868947234295527 -username [enter your Steam login ID, no square brackets] -password [enter your Steam password, no square brackets.

NOTE: This may trigger a Steam Guard event and ask you for a verification code for authentication.

4. Have patience. I encountered a LOT of "connection timeout downloading chunk: xxxxxx" type errors and a few aborted attempts by the downloader. After maybe 5-6 attempts re entering the same line above, eventually everything was validated and downloaded successfully.

5. Create a backup of your old Valheim install files (all contents of the install folder) and delete the originals.

6. Manually move the contents of the
"C:\depotdownloader-2.4.0\depots\892972\6508106" folder to the location Valheim is/was installed in step 5.

7. Restore your backups of worlds that DO NOT have "optterrain" command run in/on them.

8. Set Steam to NOT UPDATE Valheim automatically. Set it to "when I launch it" or whatever. Don't use the PLAY button in steam to launch Valheim. This may check for updates and apply them undoing all the above work!!!! Run the game using the desktop shortcut (you'll notice that also bypasses the "Vulkan" option when launching).

ENJOY OLD VALHEIM!

Apparently I can't mark my own reply as the answer to this thread. If someone could qoute me, I'll label that as the answer!
